5.1 Service Modes
The Customer Service Mode (CSM) is used for communication
between the call centre and the customer, while the Service
Alignment Mode (SAM) offers several features for the service
technician.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
5.1.1 Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV's operation settings.The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set.This helps the call centre to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
How to Activate CSM
Key in the code "123654" via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
